[Lesions resembling radial scar of the breast - Is preoperative biopsy of the radial scar needed?]

SEBŐ Éva, SARKADI László, KOVÁCS Ilona, TÓTH Dezső, BÁGYI Péter

[INTRODUCTION - The radial sclerosing lesion is one of the most common benign breast lesions. It can mimic malignant tumours on mammogram in many cases. In one third of the cases invasive tumour or in situ carcinoma occur in radial sclerosing lesion, therefore surgical excision is mandatory. The aim of our work is to diagnose the malignant cases with preoperative biopsy (FNAB, core biopsy) when radial scar morphology lesion is detected in order to avoid two-step surgical procedure. PATIENTS AND METHODS - Forty-five patients were examined with the same method. In all cases of radial sclerosing morphology lesions a mammography, complementary radiograms, ultrasonography (US) and synchronous US guided FNAB and core biopsy were performed. Postoperative pathological findings were compared to the results of preoperative biopsies. RESULTS - In 6 of 45 cases (13%) malignant tumours mimicked radial scar in morphology. All of them were diagnosed preoperatively with core biopsy (B5). The FNAB was nondiagnostic (C1) in 2 patients, suspicious for malignancy (C4) in 2 patients and was positive in 2 cases (C5). Radial scars or complex sclerosing lesions were diagnosed in 39 patients preoperatively. In 28 cases (72%), malignancy was not detected with postoperative pathological examination. In 8 cases (20%) DCIS and, in 3 cases (8%), malignant tumours were found associated to radial scar. Neither FNAB nor core biopsy gave false positive results in the non-malignant group. In the patients with DCIS associated to radial scar, core biopsy proved malignancy in 5 cases and FNAB in only 1 case. In 3 cases of invasive malignant tumour associated with radial scar core biopsy was positive in 1 patient, while FNAB was negative or non-diagnostic in all of them. CONCLUSION - According to the latest publications vacuum- assisted large-core needle biopsy (VLNB) performed with 11G needle (12) is the safest procedure to justify or exclude malignancy in the radial scar. Observation would be enough in the non-malignant cases and this procedure has therapeutic potential as well. In case where these methods are not available, as in Hungary, all radial scar cases require surgical excision. Therefore, preoperative core biopsy is recommended in order to avoid a two-step surgical procedure.]

[The effect of the orientation of the distal femur on the correction of axis after closing-wedge high tibial osteotomy - Short-medium term radiological assessment]

PAPP Miklós, KÁROLYI Zoltán, FAZEKAS Péter, SZABÓ László, PAPP Levente, RÓDE László

[Introduction - High tibial osteotomy (HTO) is a generally accepted treatment for medial unicompartmental osteoarthritis of the knee with varus alignment. The clinical result is affected by the correction of the varus malalignment. The degree of correction appears to be dependent not only on correction performed on tibia but also on the orientation of the distal femur. The valgus orientation of the distal femur can be associated with postoperative over-correction and varus orientation of the distal femur with postoperative under-correction. Patients and methods - We performed radiological assessment of 82 knees preoperatively and after closing wedge high tibial osteotomy (CWO) in the 10th postoperative week, in the 12th postoperative month and at the time of the final follow-up (23-54 months) on a standing weight-bearing anteroposterior radiograph. Pre- and postoperatively we measured the orientation of the distal femur, described as the lateral angle between the anatomic axis of the femur and the distal articular surface of the femur (FC-FS). We subdivided the knees into 3 groups based on the orientation of the distal femur. In group A the FC-FS was 83-85° (normal orientation of the distal femur), in group B the FC-FS was £82° (valgus orientation of the distal femur) in group C the FC-FS was ³86° (varus orientation of the distal femur). Pre- and postoperatively we measured the lateral angle between the anatomic axis of the tibia and the proximal articular surface of the tibia (TP-TS) and the lateral angle between the distal articular surface of the femur and the proximal articular surface of the tibia (the articular component of the varus deformity FC-TP) in all groups. We determined the anatomical femorotibial angle (FTA) as a sum of FC-FS, TP-TS and FC-TP. Results - In the first ten postoperative weeks - with significant osseous correction happened in the three groups - the articular component also decreased significantly in groups A and B, but did not change in group C. Between the postoperative 10th and the final follow-up examinations we did not notice significant osseous correction loss in any groups. In groups A and B the articular correction loss was not significant, at the same time in group C we noted significant articular correction loss. Conclusion - At valgus orientation of the distal femur the CWO results in greater correction of the limb’s anatomical axis than the osseal correction performed on the tibia. This additional correction equals the (preoperatively unpredictable) amount of the articular correction. At varus orientation of the distal femur the CWO results in less correction of the limb’s anatomical axis than the osseal correction performed on the tibia. This difference equals the (preoperatively unpredictable) loss of articular correc- tion.]

[Necrotizing enterocolitis in neonatology: comparing the role of X-ray and ultrasonographic examinations]


[INTRODUCTION - The authors’ purpose was to analyse the role of abdominal ultrasonography (US) in the diagnosis of necrotizing enterocolitis (NEC). They have compared the sensitivity of the current standard diagnostic modalities for this clinical entity: plain abdominal radiography and abdominal US. For a more objective comparison, they created an US scale along with utilising the score system based on abdominal radiography which was published recently. PATIENTS AND METHODS - 46 out of 76 neonates having both clinical and radiological diagnosis of NEC had comparable radiographic and sonographic examinations between June 2006 and October 2009. The authors created a 10-grade US score system, in which sonographic signs of NEC are listed in order of severity, corresponding, where possible with the radiographic scale that was available. The findings were scored individually, then the distribution of scores and their relationship to each other were analysed. For further analysis four groups of severity based on the scores were created with the following categories: mild, moderate, severe and very severe. After graphical representation of the groups, the relationship of the groups created on the basis of scoring the findings by the two diagnostic methods were examined. RESULTS - According to this analysis both abdominal radiographs and sonographs are suitable for diagnosing NEC, which has been justified with statistical data. When analysing the severity groups the authors proved that the two methods diverge in judging groups 3 and 4, thus severe and very severe. The distributions of severity groups formed by the two imaging modalities are different, (P<0,01); and the proportion of group 3 and group 4 is different in case of US and radiographic examinations (P=0.003). CONCLUSIONS - Abdominal sonography and radiography are equally suitable diagnostic methods for diagnosing NEC, and the two methods match each other very well. In cases of mild state, the severity of the disease was found to be the same with both methods, but US allows more sensitive differentiation of serious cases. It is very sensitive in detecting perforations, so it could play a role in determining the indication of surgery.]

[Surgical treatment of scoliosis: pre- and postoperative follow-up with whole-body EOS radiography]


[Currently, Cotrel-Dubousset spondylodesis is the treatment of choice in orthopaedics. It allows for correction of deformity in three-dimensions allowing for stable fixation. EOS (Extended Orthopedic System) is an ultra low dose X-ray imaging system, simultaneously acquiring images of the whole body in two planes. Examinations with the EOS system is not only indicated in cases related to orthopaedics but in multiple other conditions owing to its low level of emitted radiation with rapid and cost-effective imaging. The importance of EOS examination is emphasized in systemic skeletal disorders, thus allowing itt o be used in various other clinical fields.]

[Investigation of colon-transit in children with chronic idiopathic constipation]


[Constipation is a very common problem in childhood with diverse etiology. Most of the cases can be attributed to functional constipation. The types of chronic idiopathic constipation (CIC) are as follows: slow colonic transit, functional fecal retention, combination of the two and constipation which is predominant in irritable bowel syndrome. The first step in diagnosing/treating the condition should involve the exclusion of primary organic causes, as well as metabolic, neurological and iatrogenic ones. Then special anorectal physiological investigations are needed. In our laboratory, the aim of radionuclide study is to demonstrate the two types of CIC, the slow colon transit (SCT) and the functional fecal retention (FFR). Such evaluation makes it easier for the clinician to plan appropriate treatment. The radionuclide study is conducted as follows: after adequate pretreatment, Tc-99m Fyton is administered orally, and images are collected at 2, 6, 12, 24, 30 and 48 hours following administration. After the evaluation of the specific studies, exploration of the causes and exact diagnosis are established. Appropriate treatment is always planned individually. We would like to demonstrate this by presenting 3 cases.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. Our results suggest that the timing of learning and sleep plays an important role in the stabilizing process of memory representation to resist against forgetting.]
